 Description
 
 Lzip is a lossless data compressor with a user interface similar to the
-one of gzip or bzip2. Lzip decompresses almost as fast as gzip and
-compresses more than bzip2, which makes it well suited for software
-distribution and data archiving. Lzip is a clean implementation of the
-LZMA algorithm.

+files more than bzip2, and is better than both from a data recovery
+perspective. Lzip is a clean implementation of the LZMA algorithm.
 
 The lzip file format is designed for long-term data archiving and
-provides very safe integrity checking. The member trailer stores the
-32-bit CRC of the original data, the size of the original data and the
-size of the member. These values, together with the value remaining in
-the range decoder and the end-of-stream marker, provide a 4 factor
-integrity checking which guarantees that the decompressed version of the
-data is identical to the original. This guards against corruption of the
-compressed data, and against undetected bugs in lzip (hopefully very
-unlikely). The chances of data corruption going undetected are
-microscopic. Be aware, though, that the check occurs upon decompression,
-so it can only tell you that something is wrong. It can't help you

+possible for a digital archaeologist to extract the data from a lzip
+file long after quantum computers eventually render LZMA obsolete.

-Lzip replaces every file given in the command line with a compressed

+When compressing, lzip replaces every file given in the command line
